How much time would you say it takes from starting a new game until you get to enter the world and start exploring/shooting bad guys? I bought this through steam and I am not sure it will run well enough on my laptop, so I have to make sure I stay within 2 hours of gameplay so I can get a refund in case the game turns out unplayable when I reach larger/more demanding areas. If I rush through the tutorial part of the game, shoud I have some time to explore and figure out how well the game runs on my laptop?
